External authentication: We look at the example of enabling authentication using TACACS+ server as an external source. To create TACACS+ server on checkpoint first we create a Node .

In the Network Objects tab create a node, defining the IP address of the TACACS+ server

Once done you will see TACACS+ server listed under Nodes option

Go to Server and OPSEC Applications tab, right click on the Servers option, select New and click on TACACS
